Abstract

Amorphous poly(phenylene sulfide) (PPS) films were prepared by melt-pressing virgin PPS chips of high linearity and quenching into ice water. The films were annealed at $240^{\circ}C$ for up to 17 days and investigated by using a DSC. Both the melting temperature and heat of melting of PPS increased with increasing annealing time at $240^{\circ}C$, whereas the melt crystallization temperature and heat of melt crystallization decreased. Although the melting peak on heating still appeared, the melt crystallization peak on cooling disappeared after more than 10 days annealing, indicating the introduction of high degree of cross-linking. FTIR analysis and solubility tests of the annealed films also suggested the introduction of crosslinking. Increased crosslinking density refrained PPS from melt crystallization and dissolution in a solvent. Annealing at lower temperature such as $160^{\circ}C$ for up to 24 hours resulted in increasing the tensile strength of the films significantly without crosslinking. The chemical resistance of the films was almost unaffected in strong acid and alkaline solutions at $93^{\circ}C$ for 7 days.
